Stiil'ness is imparted to the housing rod 39, having its ends secured in the cover" l1 1g. 8 is. e detail side elevation as of iutercelstiug' oper by means ole tieside sills board of the housing adjacent the outer ends of the two lower sections 31 and 32 and being jointed at 40, so as not to interfere with the flexing of the hinge 34. en in use, the ortion of this tie-rod intermediate its ends is rced u wardly by means of a removable wedge b ock 41, thus giving a truss action upon the conveyer-housing.

A conveyer-belt 42 travels within the housing 25 and has secured thereto along each of its margins a sprocket-chain 48, which passes over a sprocket-wheel 44, fixed to a driving-v shaft 45, j ournaled in the sides of the housing near its lower end, and over an idle pulley 46, similarly journaled near the outer end.

Guide-pulleys 47 and 48 are employed at suitable intervals for supporting the upper and lower turns of this belt. A splice 49 is formed at a convenient point in the belt 42, which may be readily opened to permit the belt to draw up, when it conforms to the, folded position of the housing 25, previously described. An angular frame 50 is pivotally attached to the lower end of the housing 25 at 51, within which travels an endless apron 52, similar in construction to the conveyer-belt 42 and turning over sprocket-Wheels 53 and 54, fixed upon shafts 55 and 51, respectively, ournaled at opposite ends of the frame. Guide-pulleys 56 and 57 are j ournaled in the sides of the frame 50 for deflecting the apron to conform to the angular shape of the frame. Means are provided for tightening the apron 52 to insure its clinging to the various pulleys over which it turns. To this end the shaft 55 is journaled in eyebolts 58, upon the shanks of which are set-nuts 59, taking a bearing on the end of the frame.

The top of the frame 50 is left open, as shown at 60, for receiving the material to be stored, which is deposited by the apron through theopen end 61 of this frame and an opening 62 in the conveyer-housing onto the belt 42. A retaining-plate 63 is set in the housing 25 just below the opening 62 to prevent, the material falling over the end of the belt. In the drawings the outer end of the housing 25 is shown as being formed into a downwardly-turned discharge-spout 64.

The shaft 45 is continued through the wall of the conveyer-housin at one side and is providedwith a squared end 65, adapted for connection with a o iable source of power, (not shown)such, for example, as the common farm traction-engine. Motion is imparted from this shaft to the conveyor-belt 42 directly, the sprocket-wheels 44 being rigidly mounted on it, and to the traveling apron 52 by means of achain 66, passing overs rocketwheels 67 and 68, mounted on this s aft and the shaft 51, respectively.

The operation of the device is as follows: When set n for use, the arrangement of the parts is as *hown in Figs. 1 and 5, and the shaft 45 is continuously rotated, as just de scribed, to drive the conveyer-belt 42 and endless apron 52. By operating the winch 30 the conveyer-housing 25 may be raised or lowered, as may be required, to bring the discharge-spout 64 into register with the opening in the storage-bin, and the material to be deposited in the bin is thrown onto the traveling apron 52, preferably by shoveling or dumping directly from the body of a wagon. (Not shown.)

To prevent backing or turning a heavilyloaded wagon, the apron-housing 50 may be raised, as shown by dotted lines in Fig. 1,

while the wagon is driven by the lower end of the conveyor to such a position that its contents may be conveniently unloaded onto the apron, when the housing is again lowered into position.-

lVhen the device is not in use or when itis to be transported from place to place, the

coi fveyer and apron housings may be folded to a compact form upon the truck 15, as follows: The housing 25 is first lowered by operating the winch 30 so as to allow the cables 26 and 27 to unwind, the splice 49 in the belt is opened, the pin 38 withdrawn to al- .low the hinge 34 to flex, and the block 41 is removed. Now by first winding on the winch 30 and then releasing it the part of the housing above the hinge 34 may be laid over on the lower section 31, after which the upper section 33 and the apron-housing 50 may be turned forwardly and the uprights 1S and 19 ma r be laid down parallel to the side sills 16 an 17 by removing the diagonals 21 and 22.

In order that the parts of the conveyerhousing may rest substantially horizontal when folded and to permit of raising and lowering the foot of the conveyor to compensate for slight unevenness of the ground when the device is in use, the rear axle of the truck 15, supporting the conveyer, is bent downwardly, as indicated at 69, Figs. 3 and 4, and a hand-lever 7 O is provided for turning this axle.

A pawl 71 is pivotally attached to the hand-lever 70 to play over a toothed segment 72, secured to the wagon-truck, and is controlled by a grip-piece 73.

It may sometimes be found convenient to provide the diagonals 21 22 with hinges, as 74, Fig. 9, intermediate their ends, which flex downwardly and may permit the uprights 18 and 19 to be laid down parallel to the side sills 16 and 17 without removing these diagonals.

A tongue 75 is provided with the truck 15, 'to which draft-animals may be attached for hauling the folded conveyer about. it This application is a division of my application, Serial No. 237,318, filed December 17, 1904.
